Two Piece Shield - Custom Precision EMI Shielding Case for Electronics

Product Overview

Two Piece Shield is a professional split-type electromagnetic interference (EMI) shielding case specially designed for electronic circuit boards, belonging to a core protective component for precision electronic equipment. Shielding cases on the market are mainly divided into single-piece and two-piece structural forms, and the two-piece model is a high-practicality customized solution developed for scenarios requiring subsequent hardware debugging and post-maintenance. This shielding case adopts a separate frame and cover assembly structure, which solves the contradiction between shielding effectiveness and later maintenance, and is widely used in various precision electronic products with high requirements for circuit stability and maintenance convenience.

We have many years of professional experience in the design, mold development and mass production of shielding cases, and have a deep understanding of the structural design, electromagnetic shielding performance and assembly requirements of such components. Our company is equipped with an independent precision stamping mold shop and a professional mold R&D team, which can provide customers with a full-package one-stop service covering product design, mold manufacturing, precision stamping production, post-processing to final assembly and packaging. We have a stable monthly delivery capacity of 1.5 million pieces, which can fully meet the large-scale supporting procurement needs of electronic manufacturers, and always adhere to the goal of becoming the world's most professional precision stamping mold and product supplier, helping customers improve product competitiveness.

Core Product Functions

The Two Piece Shield undertakes multiple core functions in electronic circuit applications, focusing on electromagnetic interference shielding, circuit grounding protection, PCB module protection and convenient later maintenance, which is crucial to ensure the stable operation of precision electronic equipment. Primarily, it realizes efficient electromagnetic shielding, effectively isolates external electromagnetic wave interference and internal circuit radiation conduction, avoids RF (radio frequency) problems such as signal interference and abnormal radiation caused by poor shielding, and ensures the stability and accuracy of circuit signal transmission.

Secondly, it undertakes the core circuit grounding function: the frame part is directly welded to the PCB board as a fixed grounding (GND) terminal, forming a stable grounding path to eliminate circuit potential safety hazards and signal abnormalities caused by poor grounding. In addition, the split structure gives it unique maintenance advantages, which is convenient for technicians to disassemble and assemble the cover quickly during hardware debugging and later after-sales maintenance, without damaging the welded frame and PCB board, greatly reducing maintenance difficulty and cost. It also provides physical protection for internal PCB modules, preventing extrusion, dust and damage during use and handling.

Key Structural & Production Features

This Two Piece Shield has targeted structural design and production advantages, focusing on firm assembly, reliable welding, anti-falling and anti-RF failure, completely meeting the high-standard use requirements of electronic equipment. In terms of structural design, the frame and cover adopt a side wall buckle assembly mode, with precision stamped emboss and slot matching structure, ensuring tight and firm fit between the frame and cover, avoiding loose fitting or falling off, and smoothly passing the product drop test to eliminate potential safety hazards caused by cover falling.

Material selection is matched with functional requirements: the frame part is mainly made of nickel silver material, which has excellent tin soldering performance, ensuring firm and stable SMT welding with the PCB board, and perfectly matching the grounding needs; the cover part can be made of cost-effective tinplate, and stainless steel and other materials are also available for customized selection, balancing performance and production cost. We adopt high-precision progressive stamping process for production, with stable size and smooth surface without burrs, no additional post-treatment is required, and the production efficiency is high to meet large-scale order needs. The strict structural design also avoids poor contact between the frame and cover, effectively solving RF problems such as radiation conduction caused by poor grounding.

Product Specifications & Production Capacity

This Two Piece Shield is a purely OEM customized product, with no fixed unified standard specifications, and all dimensions, shape and structural details are formulated according to customer-provided drawings or physical samples. The optional materials include nickel silver (for frame), tinplate (for cover), stainless steel and other electronic special shielding materials, customers can choose according to product performance and cost needs. The core production process is high-precision progressive stamping, no additional post-treatment is configured by default, and targeted surface treatment can be added according to special customer needs.

Conventional performance testing is not configured by default, and customized testing can be arranged according to customer special shielding and assembly requirements. We provide two conventional packaging methods: tape and reel packaging suitable for automated SMT assembly, and conventional PE bag packaging, customers can choose according to production and assembly needs. This product is dedicated to the electronic industry, with a stable monthly delivery capacity of 1.5 million pieces, which can meet the long-term large-scale supporting needs of electronic equipment manufacturers and ensure stable and consistent batch product quality.

Application Scenarios

This Two Piece Shield is widely used in various electronic equipment fields that require electromagnetic shielding and later maintenance debugging, especially suitable for precision electronic products with high requirements for circuit stability and convenient after-sales. Main application scenarios include consumer electronic equipment such as mobile phones, tablets, smart wearable devices, communication terminal equipment, industrial control electronic circuit boards, automotive electronic modules, small household appliance control boards and other precision electronic products. It is especially suitable for electronic products that need frequent hardware debugging, signal testing and later maintenance, replacing the single-piece shielding case that is difficult to disassemble, and taking into account both shielding effectiveness and maintenance convenience.
